Only put 200 miles on this beast this past winter but this machine has impressed me so far. This 800 starts and runs extremely well and pulls very hard low and mid. Get a lot of studs. It's down a few ponies from Cats and E-TECS but no need to worry...it stays with them and will sometimes even take them. I can't comment much on fuel economy but oil mileage seems incredible. You can just pound the rear suspension without bottoming it out and the front end is razor sharp. Only gripes are intermittent vibes from the recoil handle area and the fuel gauge is a little wacky. All in all, it's a great sled and I can't wait to do some more suspension tweaking this winter.
